CUT-OFF FOR BOLTlNG-CHESTS.

5PECIFICATION forming part of Letters Patent No. 303,764, dated August19, 1884.

Application filed April 12,

To all whom it may concern.-

Be it known that I, J OHN TODD, a citizen of the United States, residingat Lewistown, in the county of Mifflin and State of Pennsylvania, haveinvented certain new and useful Improvements in Out-Offs forBelting-Chests; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Figure 1 represents a central vertical section showing my improvement.Fig. 2 is a plan view of one of the feed-slides or cut-offs, and Fig. 3is a detailed perspective view, hereinafter referred to.

My invention relates to cutoffs for boltingchests; and the improvementconsists in the following construct-ion and arrangement, the points ofnovelty of which are set forth in the claim.

The present invention is an improvement upon a former device foraccomplishing the same object, and for which application was madeJanuary 80, 188i.

In the accompanying drawings, a represents the hopper-boards of thebolting-chest, which are located beneath the reel. (Not shown.) Theboards a are secured to the pieces b,.whieh form the upper walls of thecut-oft slides.

0 represents the cut-01f slides, each of which is capable of independentoperation.

(I are the inclined end walls, arranged as shown, whereby the flourproducts may be changed from one conveyor to the other by thelongitudinal movement of the valve.

6 are the vertical side walls of the valve or cut-off. Each valve has apartition or wall at either side. These partitions are made of thinsheet-iron, and the adjacent walls of each valve contact each other.

by the introduction 1884. No model.)

is a saddle-piece, made of sheet-iron, and rigidly secured in anysuitable way to the hopper-boards a, and embraces the contiguouspartitions 6 between it. This saddle-piece projects below the lower endof the hopperboards, where it acts as an efie'ctnal stop to the forwardand backward movements of the slides. This construction economizes agreat deal of space and effectually prevents any leakage of the flourproducts between the series of valves.

9 are doors for closing the openings made of the valves.

h and z are the conveyer-troughs, arranger beneath the cut-offs so thatthe flour products may be changed from one conveyor to the other atpleasure by the operation of the valves.

It will be seen that by the employment of cut-offs having thinsheet-iron sides a great saving in space is obtained; and further, thatby the employment of the saddle'pieees be tween the valves a veryefficient means is at the same time secured to prevent any leakage ofthe flour, or any clogging of the valves in their movements.

1 claim- The combination, in a cut-off for flour-bolting apparatus, of aslide having the converging sides (1 d, the converging hopper-boards a.and a saddle-piece, f, straddling the sides of the slides and projectingbelow the edges of the boards (0, thereby forming a stop to arrest themovement of the slide in either direction, substantially as described.

In testimony whereof I aifix my signature in presence of two witnesses.

JOHN TODD.
